You can have it all! We have looked high and low for a beautiful and practical metal pet gate. We even considered designing and making our own until we came across these.Worth the money, and they work. We purchased 2 of these and also 2 of the tall/walk through gates. Just perfect!

Are the side panels included in the max. 40"/70" widths or can I use the smaller version to close a 5' opening if I leave the side panels at an angle?

How long is the smaller version with the two side panels straight with the center panels? Or, when the gate is placed flat on the floor, how long is the entire gate (panels flat as well)? Is that how you measure the maximum widths (small 40" and large 70") with the side panels included in the measurement?

I think you want to know if this gate will cover a wider width than it's specified? It fits the widths specified with the sides/feet perpendicular to the panels (as pictured). The side panels are not made to be lined up with the main panels and are not part of the width covered. If you need a wider width like I did (60" without having to hurdle over a gate) I purchased the tall/walk through wider gate. Both are Very worth the purchase.
